Application filed February This invention relates to an improved construction of pipe bowl cleaner; and has for its object to provide a cleaner of this character which is formed ot a length o1 wire folded upon itself and having an operating handle, those portions of the wire adjacent the handle being twisted and their end portions or scraping arms being yieldable and shaped to enter and lit the bowl of a pipe to scrape the walls thereof when rotated, the crossing of the wires at the twist being arranged so that one wire will lie upon the other to support one another against a scraping strain.

Y A further object of the invention is to fold the wire to form a crossbar handle and to twist that portion of wire adjacent the handle so that each wire will lie over and under the other to permit a free radially yielding action of extended length back through the twisted shank to the handle portion, the pipe bowl engaging portion of the wire being flattened providing cutting or scraping edges to clean the inner surface of the bowl and to readily yield radially to fit bowls of different sizes and to fit down into and clean the bottom of the bowl.

lVith theseand other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 2 is a view showing this pipe cleaner as positioned in the bowl of a pipe shown in dotted lines.

It is found in practice that the smoking of a pipe causes the inner walls of the bowl to become encrusted and that it is of advantage to provide a simple and effective 2, 1928. Serial No. 251,319.

scraper which may be yieldingly inserted into the bowl of a pipe and rotated to scrape and remove this encrustation and that-the same be so formed that it will flexibly fit the larger portion 01 the bowl and also be adapted to be compressed as to also lit the smaller portion of the bowl and scrape the bottom thereof and to accomplish this in a simple and effective way. e have provided a pipe bowl cleaner which is formed of a length of wire which may be folded to form a cross bar handle if desired and those portions oi the wire adjacent the handle being twisted and their lower port-ions curved outwardly and flattened to form yieldable scrapers, the wires at the twist each supporting the other against the twisting or working strains and at the same time permitting a tree radial yielding motion to exert the proper scraping pressure against the walls of the bowl; and the following is a detailed description of the present embodiment of my invention and showing a simple and effective construction of cleaner by which these advantageous results may be obtained.

} Our improved cleaner may be formed from a length of wire which may be round or of any other shape in cross section, the same being preferably folded upon its middle portion to form a loop-shaped cross bar 10. The two portions of wire 11 adjacent the handle being twisted together to lie over and under each other and the end portions 12 which are extensions of the twisted shank are curved outwardly and oppositely with their extremities 13 adjacent each other. These curved portions being preferably flattened as at lat, see Fig. 5, to provide scrapin edges 15.

By twisting the shank portion so that the wires will he one upon the other these wires support each other against displacement while under the working strain of their scraping action. By forming the cross-bar handle in open loop form it presents a broad surface to the twisting action of the operator. Also, by reducing the extremities 13 of the scraping arm's they are permitted to yield and conform to the shape of the pipe bowl to be engaged when forced into the bowl to clean the bottom portion thereof.

Our improved pipe bowl cleaner is extremely simple and inexpensive in construction and yields radially in its action to fit different sizes of pipe bowls and its reduced size permits it to take up the minimum amount of space in the pocket of the user.

The foregoing description is directed solely towards the construction illustrated, but we desire it to be understood that we reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

WVe claim:

1. A pipe bowl cleaner having an operating handle and having wire members below the handle twisted together to form a shank and the endportion of the wire members below the shank having scraping edges and curved outwardly to fit into and yieldingly engage and scrape the walls of a pipe bowl.

2. A pipe bowl cleaner formed of a length of wire folded near its middle portion to form a loop-shaped handle, the two portions of the wire below the handle being twisted together to form' a shank and the end portion of the wire being curved outwardly to fit into and yieldingly engage and scrape the walls of a pipe bowl, said engaging portions being shaped to provide scraping edges.

8. A pipe bowl cleaner formed of a length of wire folded upon itself near its middle to form a cross-bar handle, the two portions of wire adjacent the handle being twisted together and the end portions of the wire being curved outwardly to yieldingly engage and scrape the walls of the pipe, the wires at the twist being positioned to lie agains and support each other in working position against a rotating scraping action.

4. A pipe bowl cleaner formed of a length of wire folded upon itself to form a loopshaped cross-bar handle those portions of the wire adjacent the handle being twisted and their end portions rounded outwardly oppositely and shaped to form yielding scraping edges to enter the pipe bowl, the wires at the twist lying one upon the other to support each other against a working strain and also being free to slide one upon the other and permit each scraping end portion an extended radially yielding action back through the twist to the handle portion. I

5. A pipe bowl cleaner comprising a single piece of wire folded to form a loop handle with its oppositely extending portions twisted over and under each other and extended generally at right angles to said handle to form cleaning arms with a curvature suitable to fit a pipe bowl, the points of crossing of said twisted portions being spaced to allow relative andresilient movement of the arms toward each other.

In testimony whereof, we afliX our signatures.
